-Subject: [PATCH 5/6] drm/i915: improve the catch-all evict to handle lock
- contention
-
-The catch-all evict can fail due to object lock contention, since it
-only goes as far as trylocking the object, due to us already holding the
-vm->mutex.  Doing a full object lock can deadlock the system, since the
-vm->mutex is always our inner lock. Add another execbuf pass which drops
-the vm->mutex and then tries to grab the object will the full lock,
-before then retrying the eviction.
